May-December Celebrity Romances

Mary-Kate Olsen and Olivier Sarkozy

Ages: He's 46. She's 29.

The Olsen twins are all grown up! In fact, one half of the "Full House" cuties is now married to her long-time beau Olivier Sarkozy, a banker who also happens to be the brother of former French Prime Minister Nicolas Sarkozy. And though Olivier is from France, don't hold your breath thinking Mary-Kate is moving there any time soon. Her fashion business with sister Ashley is booming, and she told Allure, "It's not like you wake up one day and have a huge company with four or five different companies within the companies."
